A hip belt is the padded waist belt on a backpack that transfers most of the load from the shoulders to the hips, where the body carries weight far more comfortably. On a loaded pack the hip belt should bear the majority of the weight — getting its fit and position right is the single biggest factor in carrying comfort.
A daypack is a small backpack, typically 10-30 litres, used for day hikes and short outings where you don't carry overnight gear. It holds the essentials — water, food, layers, and the Ten Essentials — and is light and simple, often without the frame or heavy hip belt of a multi-day pack.
Layering is the system of wearing multiple clothing layers — a wicking base layer, an insulating mid layer, and a protective shell — that you add or remove to regulate temperature and moisture outdoors. Layering lets you adapt to changing weather and exertion, and is the foundational principle of dressing for the backcountry.
Microspikes are lightweight traction devices — elastic harnesses with small chain-mounted spikes — that slip over shoes or boots for grip on packed snow and icy trails. Far lighter and less aggressive than crampons, they're ideal for winter hiking and trail running on rolling terrain, but not for steep snow or ice climbing.
A headlamp is a head-worn light that frees your hands for tasks in the dark — hiking before dawn, setting up camp, or navigating at night. Measured in lumens for brightness, modern LED headlamps offer multiple modes and run on disposable or rechargeable batteries. It is one of the Ten Essentials.
Fleece is a soft, breathable synthetic (polyester) knit used as a warm, quick-drying mid layer. It insulates even when damp, breathes well for active use, and is durable and affordable, though it is bulky and not windproof. Fleece comes in weights from light grid fleece to heavy jackets.
A synthetic jacket is insulated with man-made fibers that mimic down, offering reliable warmth that — crucially — keeps insulating even when wet and dries fast. Synthetics are cheaper and more weather-tolerant than down but heavier and bulkier for the same warmth, making them ideal for damp climates and active use.
A down jacket is insulated with down — the soft, lofty plumage under bird feathers — giving the best warmth for its weight and packing down very small. Down's weakness is moisture: it loses loft and warmth when wet, so it excels in cold, dry conditions and is often paired with a shell or treated to be water-resistant.
A rain jacket is a waterproof, breathable outer layer designed to keep you dry in rain. It uses a waterproof membrane or coating and taped seams, with a DWR finish that makes water bead off the surface. Rain jackets range from light packable shells for emergencies to burly hardshells for sustained storms.
A softshell is a stretchy, breathable outer jacket that blocks wind and sheds light moisture while letting you move freely, ideal for active use in dry or variable conditions. Softshells trade the full waterproofing of a hardshell for comfort, breathability, and durability, making them popular for climbing, hiking, and ski touring in fair weather.
